Maybe a minority but I used Lecturio pretty extensively during my first year and I ended up in the top 1/4 of my class. It’s actually more detailed than you need to know in a lot of the disciplines (anatomy and biochem, I’m looking at you). I really used Lecturio in place of class lectures for both physio classes, too, and I pulled As.
I don’t think it’s a must, though. You can find a lot of the same info other places. I used it a little bit during second year, mostly if I wanted to find a video on a really specific topic I didn’t think was explained well enough on UWorld. I didn’t really run into any wrong info that I’m aware of, but I guess I just didn’t know what I didn’t know. Also did fine on boards (247/735) so they didn’t do me too dirty.
I actually go out of my way to recommend their cranial videos. I think that’s all the cranial I needed to know to do well on cranial on the OMM comat and the comlex level 1. They do the hand movements and the movements of the SBS and the axes of rotation, which were 99% of the cranial I was tested on and they explained it way better and faster than my class lectures. Also 100% got a COMAT question right because they gave the exact scenario that I got on the COMAT for that particular cranial dysfunction.
edit: LOL, didn’t realize this thread was old.
